Bouvier's Law Dictionary, Revised 6th Ed (1856):

VISNE. The neighborhood; a neighboring place; a place near at hand; the
venue. (q.v.)
     2. Formerly the visne was confined to the immediate neighborhood, where
the cause of action arose, and many verdicts were disturbed because the
visne was too large, which, becoming a great grievance several statutes were
passed to remedy the evil. The 21 James I, c. 13, gives aid after verdict
where the visne is partly wrong, that is, where it is warded out of too many
or too few places in the county named. The 16 and 17 Charles II. c. 8, goes
further, and cures defects of the visne wholly, so that the cause is tried
by a jury of the proper county. Vide Venue.
